python
denied_slots_after_decay(db: PrefectDBInterface) -> ColumnElement[float]

Calculate denied_slots after applying decay.

Denied slots decay at a rate of slot_decay_per_second per second if it's greater than 0 (rate limits), otherwise for concurrency limits it decays at a rate based on clamped avg_slot_occupancy_seconds.

The clamping matches the retry-after calculation to prevent denied_slots from accumulating when clients retry faster than the unclamped decay rate.
